South Korean firefighters managed to install an air mattress just in time to help a young man who jumped from the roof of an 18-story building, rescue authorities in South Chungcheong Province said Tuesday.

Officials at the Nonsan Fire Station received a report at around 2 p.m. Sunday that a man was attempting to jump from an apartment building. Firefighters arrived to find the man in his 20s sitting on the building's roof.

One of the rescue workers approached the man to persuade him not to jump while the others installed an inflatable air mattress below. The man fell from the building onto the air mattress that was installed just in time. He did not sustain serious injury.

Chief Kim Gyeongseol of the fire station said that the firefighters were able to respond promptly thanks to repeated training for similar situations, such as emergency response for highly populated areas like apartment complexes.
